Causes

Craniosynostosis is often classified as nonsyndromic or syndromic. Nonsyndromic craniosynostosis is the most common type of craniosynostosis, and its cause is unknown.

However, syndromic craniosynostosis is a complication caused by certain genetic syndromes, such as Apert syndrome, Pfeiffer syndrome and Crouzon syndrome, which can affect your baby's skull development.
